Abstract: An optical encoder includes a light source fiber holder holding a light source fiber and a collecting lens therein, and a nut. The light source fiber holder includes an end fitting together with a light source base. An outer circumferential surface of the end includes an inclined surface inclining such that a cross-sectional area increases as the surface approaches the light source fiber; and a projection capable of advancing into a groove of the light source base. The optical encoder includes a light source connector and the light source fiber holder.

Abstract: An optical encoder includes a scale having bar-like scale marks; a detection head having a light source fiber emitting coherent light at the scale and a photoreceiver fiber receiving light reflected off the scale; electronic components connected to the detection head via the light source fiber and the photoreceiver fiber; and a protector covering the scale marks at a predetermined distance from the scale marks. The protector is a member configured with light-transmissive material and includes a top surface that is inclined with respect to a principal surface of the scale.
